AI Technical Summary
When dealing with high-speed, highly maneuverable targets, existing technologies often suffer from poor detection performance due to distance ambiguity in traditional coherent accumulation algorithms, making it difficult to effectively detect such targets.
A high-speed target accumulation detection method based on remainder processing is adopted. By constructing a radial motion model and applying the MGRFT algorithm for coherent accumulation, the range migration and Doppler migration are corrected to achieve energy accumulation of the echo signal.
It significantly improves the radar's detection performance in low signal-to-noise ratio environments, effectively eliminates the effects of range ambiguity and Doppler ambiguity, and enables effective detection of high-speed targets.
